The shaded region of the design shown is to be painted red. What is the area, in square units, of the shaded region? (Use = 3.14) A 43.0

B 62.8

C 121.5

D 137.2

A.43.0

Step-by-step explanation:

area of rectangle= l*w=10 units *20 units= 200 units^2

area of the 2 circles:

diameter= 20/2=10 units

r=d/2= 10/2=5 units

area of a circle= 3.14*r^2

=3.14*5*5

=78.5> the 2 circles are identical then they have the same area

area of the shaded region= area of the rectangle- 2*area of one circle

= 200- (2*78.5)

=200-157

=43.0

therefore the area of the shaded region is 43.0 units^2

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
